Abstract

The invention relates to a biological agent for preventing pests and diseases in a tea garden and a preparation method thereof and belongs to the technical field of biological agents. The biological agent is composed of, by mass, 1.8-2.2% of essential oil of wild ginger, 6-10%of essential oil of aiphyllium plants, 2.8-3.2% of essential oil of litsea cubeba and the allowance of solvent, and the total mass percentage is 100%; the essential oil of aiphyllium plants is essential oil of eucalyptus leaves or wild cinnamons or camphor leaves; the solvent is ethyl alcohol or a mixture of ethyl alcohol and water. The preparation method is simple and reliable; the prepared biological agent can effectively prevent pests and diseases from appearing in the tea garden, has high application value and is easy to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of biological preparations and relates to a biological preparation, in particular to a biological preparation for preventing and controlling pests in tea gardens and a preparation method thereof. Background technique [0002] my country's crops use more than 800,000 tons of chemical pesticide preparations every year, 80% of which are highly toxic pesticides, resulting in more than 20% of crops such as fruits, vegetables and tea leaves exceeding the standard. In recent years, as people put forward higher requirements for food safety and environmental safety, biopesticides have also developed rapidly. Biological pesticides are living organisms and their metabolites used to prevent and control harmful organisms such as diseases, insects, and weeds, and can be made into commercially available biological source preparations. By 2015, the share of bio-pesticides in all pesticides in my country will increase to 30...
